If I did wrong interpret the problem please tell me thx..

Code: Select all

#include<iostream>
#include<stdio.h>
#include<stdlib.h>
#include<vector>
#include<algorithm>
using namespace std;

int main(){
	int n;
	vector<long long> diff;
	while(scanf("%d",&n)!=EOF){
		bool jolly=0;
		long long before;
		scanf("%lld",&before);
		for(int i=1;i<n;i++){
			long long after;
			scanf("%lld",&after);
			diff.push_back(abs(after-before));
			before=after;
		}
		sort(diff.begin(),diff.end());
		if(diff.back()>=n){
			jolly=0;
		}else if(n==1){
			jolly=1;
		}else if(n!=0){
			for(int i=1;i<n-1;i++){
				if(diff[i-1]==i){
					jolly=1;continue;
				}
				else{
					jolly=0;break;
				}
			}
		}else jolly=0;
		if(jolly) printf("Jolly\n");
		else printf("Not jolly\n");
		diff.clear();
	}
	
	return 0;

You need to initialize differ

[Ovro]

Thanx a lot sir. I should have figured it out myself.

4 1 4 3 5 is Jolly

[abbir.ku]

For the input 3 1 3 6 the answer is jolly I think . After having some trouble I figure out one just have to check absolute difference is 1 or not .

anyone can help mee? I still didn't realize where my mistake, my code still gave me WA ....

#include<cstdio>
#include<iostream>
#include <cmath>

using namespace std;

int n,arr[3010],k,x;

int main () {
while (scanf("%d",&n) != EOF ) {

scanf("%d",&arr);
}

bool nilai=true; k=0;
for (int i=0; i < n-1; i++) {
x=arr[i+1]-arr;
x= abs(x);
k++;
if (x==n-k) {continue;}
else {nilai =false; break;}

}

if (n==1) {nilai = true;}

if (nilai) {printf("Jolly\n");}
else {printf("Not jolly\n");}
}



return 0;

Don't double post

why i got WA answer in jully jumber ....

the problem ask to find two successive elements their difference BW 1 to n-1

whta's the wrong !!!
